Plot eye gaze trace from positional data.

Parameters:

  • gaze (GazeDataFrame) – The GazeDataFrame to plot.

  • position_column (str, optional) – The column name of the x and y position data

  • cval (np.ndarray) – line color values.

  • cmap (matplotlib.colors.Colormap, optional) – color map for line color values

  • cmap_norm (matplotlib.colors.Normalize, str, optional) – normalization for color values.

  • cmap_segmentdata (dict, optional) – color map segmentation to build color map

  • cbar_label (str, optional) – string label for color bar

  • show_cbar (bool) – Shows color bar if True.

  • padding (float, optional) – Absolute padding value. If None it is inferred from pad_factor and limits.

  • pad_factor (float, optional) – Relative padding factor to construct padding value if not given.

  • figsize (tuple) – Figure size.

  • title (str, optional) – Figure title.

  • savepath (str, optional) – If given, figure will be saved to this path.

  • show (bool) – If True, figure will be shown.

Raises:

ValueError – If length of x and y coordinates do not match or if cmap_norm is unknown.
